它无法 post 使用 JS 表单提交功能
It is not able to post with JS form submit function
在这个网页中,我有一个带有提交按钮的可见表单,称为表单 A.It 有一个 post 操作。
<form name="payFormCcard" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]); ?>" method="post">
我想做一个隐藏的表单,从表单A中提取一些数据,使用隐藏输入按钮的方法。它自动执行表单并post到另一个地方用JS。
但是,如果我添加真正的按钮,它会工作并且 posts 到适当的位置。
<input type="submit" name="submission_button" value="Click here if the site is taking too long to redirect!">
这是我的代码(没有真正的按钮):
<form name="A" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]); ?>" method="post"> <== first visable form
.....
//invisible table
<form name="payForm" method="post" action=" https://test.paydollar.com/b2cDemo/eng/payment/payForm.jsp">
<input type="hidden" name="merchantId" value="sth">
<input type="hidden" name="amount" value="</?php echo $input_amount; ?>" >
<input type="hidden" name="orderRef" value="<?php date_default_timezone_set("Asia/Taipei"); $date = date('m/d/Y h:i:s a', time()); echo $date ; ?>">
<input type="hidden" name="currCode" value="sth" >

<input type="hidden" name="cancelUrl" value="http://www.yourdomain.com/Cancel.html">

<!-- <input type="submit" name="submission_button" value="Click here if the site is taking too long to redirect!">-->
</form>
<script type="text/javascript">
//Our form submission function.
function submitForm() {
document.getElementById('payForm').submit();
}
//Call the function submitForm() as soon as the page has loaded.
window.onload = submitForm;
</script>
您应该使用 DOMContentLoaded instead of load 来确保 DOM 元素加载成功。
尝试执行如下操作:
<script type="text/javascript">
//Our form submission function.
function submitForm() {
document.getElementById('payForm').submit();
}
//Call the function submitForm() as soon as the document has loaded.
document.addEventListener("DOMContentLoaded", function(event) {
submitForm();
});
</script>
